LAN Emulation Interface

LAN Emulation, which provides mechanisms to send broadcast messages, is another way of supporting the TCP/IP and UDP/IP protocols over an ATM network. A series of LAN Emulation services (such as the LAN Emulation Configuration Server -LECS-, the LAN Emulation Server -LES-, and the Broadcast and Unknown Server -BUS-) provide address resolution information. When a LAN Emulation interface is brought up, it joins the LAN by registering with these services. The LAN Emulation protocol provides a broadcast service to the upper layer protocols. Therefore, a LAN Emulation interface is not affected by the multicast and RIP limitations of Classical IP.

Each ATM port on the Netra server currently supports only one LAN Emulation interface.
